Stop truncating quote-tweet text, keep media at thumbnail size

extractQuotedTweet() was capping the quoted tweet's text at 240
characters via toSummary(); it now keeps the full cleaned text,
matching the outer tweet's own body which was never truncated.
Dropped the matching -webkit-line-clamp: 3 on .quoted-text in
TweetCard.svelte so the full text actually renders instead of being
clipped after 3 lines. Media sizing (.quoted-img's 140px cap, the
media grid's fixed cell heights) is unchanged — only text was meant
to stay unconstrained.
